Break circular dependency between owner-report.scm and reports.scm

That is:
* move the account lookup from report.scm to owner-report.scm so
there's no need any more to call into reports.scm from within owner-report.scm
* fix the cmake dependency tree to reflect the new changes:
only customer-overview depends directly on code in reports.scm
All other reports don't. reports.scm however does depend on three
standard reports. So:
standard-reports <- reports <- customer-overview
